3-in-1 Pressure and Vacuum Gauges

These portable gauges have three different dials to display pressure and vacuum measurements on a low, medium, and high scale.

Flow Monitoring

High-Pressure Flowmeters for Air

Rated for at least six times the pressure of standard flowmeters for air, these can withstand pressures of at least 600 psi.

Full-View Flowmeters for Water

The transparent body lets you inspect water color and clarity in addition to measuring the flow rate.

Easy-to-Install Full-View Flowmeters for Water

Union nuts on both ends make it easy to install and remove these flowmeters from your system.

High-Pressure Flowmeters for Water

Rated for pressures up to 3,500 psi.

High-Pressure Flowmeters for Oil

Designed for more than 10 times the pressure of standard flowmeters for oil, these are rated for pressures up to 3,500 psi.

Flowmeters for Oil

Measure the flow rate of hydraulic and motor oil.

High-Temperature Flowmeters for Oil

With double the temperature rating of standard flowmeters for oil, these can be used with oil up to 400° F.

Compact Flow Sights with Indicator for Water and Oil

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present.

Compact Flow Sights for Water and Oil

The low-profile body fits in areas with limited clearance.

Full-View Flow Sights with Indicator for Water and Oil

A ball indicator increases the visibility of flow for checking at a distance.

Level Monitoring

High-Pressure Oil-Level Indicators

Monitor hydraulic fluid or oil level in pressurized applications.

Oil-Level Indicators

Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs.

High-Pressure Oil-Level and Temperature Indicators

These indicators mount from the outside of your tank.

Oil-Level and Temperature Indicators

Simultaneously monitor hydraulic fluid or oil level and temperature in gear boxes, crank cases, and other reservoirs.

High-Visibility Sights

Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window.

Sights

These sights have a glass window.

Pressure Gauges for Hydraulic Jacks

Monitor hydraulic oil pressure levels to guard against overload. These gauges are liquid filled to reduce needle vibration and include an adapter to mount the gauge in line with the hose.
